Oil starvation seems the culprit. It would be interesting to know how the oil supply path goes in this motor. Could it potentially also affected other bearings in the engine, or do they think it's just limited to the turbo oil feed?
At Melrose I thought it might have been swarf or something in the oil galleries or a restrictor which causes the intermittant low oil pressure to the turbo.
If you have any input on how the issue is rectified, It would be interesting to see an oil analysis done to see if there is any other damage (signs of bearing material, and if possible if it can differentiate between turbo bearings and big end / main bearings). Also see what the oil filter has collected once cut open.
Once dealer involvement with the car ceases (ie out of warranty), might be worth investigating some sort of oil pressure sensor on the turbo oil feed line, hooked to a big red light and buzzer :cool:
